N2 - We introduce a galaxy cluster mass observable, mu(*), based on the stellar masses of cluster members, and we present results for the Dark Energy Survey (DES) Year 1 (Y1) observations. Stellar masses are computed using a Bayesian model averaging method, and are validated for DES data using simulations and COSMOS data. We show that mu(*) works as a promising mass proxy by comparing our predictions to X-ray measurements. We measure the X-ray temperature-mu(*) relation for a total of 129 clusters matched between the wide-field DES Y1 redMaPPer catalogue and Chandra and XMM archival observations, spanning the redshift range 0.1
